BRUSHLESS MOTOR

WIPO Patent Application WO/1993/011597

A1

A structure of the terminals of a brushless motor, which enables the motor to be thin and enables the windings of the motor to be connected to a circuit base board easily and automatically. The brushless motor comprises a rotor section, a stator section, a driving circuit (18), a terminal (6), and a core holder (5). The rotor section has a rotor magnet (7). The stator section has a winding (4) opposed to the rotor magnet (7) in the radial direction of the motor and has a stator core (3) around which the winding (4) is wound. The driving circuit (18) is formed on the surface of a circuit base board (9) electrically connected to the winding (4) wound around the stator core (3). Each terminal (6) has a holder (6b) and a connection part (6c). The holder (6b) holds the winding (4) and is electrically connected to the winding (4). The connection part (6c) is electrically connected to a land part (19) of the driving circuit (18). The core holder (5) holds the terminals (6). The terminals (6) are provided on the surface of the core holder (5), the surface being opposed to the circuit base board (9). At least the holder (6b) and the connection part (6c) are in parallel with the circuit base board (9), and the connection part (6c) is nearer to the circuit base board (9) than the clip-type holder (6b).
